Yool contradicts himself in episode 19. He actually makes me angry sometimes. I understand he love Chaekyung, but he doesn't seem to get she love Shin, but as I was saying he says that time will change everything, meaning even if Shin felt the same ways about her now, later on he won't feel that way. Well if time changes everything, doesn't that mean his love for her will change as well? Aigoo! So annoying!
